WAGON RUNNING-GEAR.

SPECIFICATION forming part of Letters Patent N 0. 641,771, dated January23, 1900. Application filed June 8,1897. Serial No. 639,835. (No model.)

T0 on whom it nutyooncern:

-Be it known that I, STEPHEN M. HARRIS, a citizen of the United States,residing at Cheney, in the county of Spokane and State of Washington,have invented certain new and usefulImprovementsinWagonRunning- Gear;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompany:

My invention consists in the novel construc:

tion and arrangement of parts substantially as set forth, whereby thedisadvantages of the described arrangement of the parts is avoided, thelife of the wagon increased, and the solidity of the parts insured.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a plan View of a wagon constructed in accordance with myinvention. Fig. 2 is a plan View of the bolster separated from therunning-gear. Fig. 3 is an inverted plan view of the bolster. Fig. 4. isa plan view of the cross-piece'of the hounds. Fig. 5 is a plan View ofthe axle of the wagon, and Fig. 6 is a transverse sectional View.

In the drawings, A represents the bolster, which in general form is thesame as that ordinarily used. In constructing a wagon in accordance withmy invention the bolster is provided both on its front and rear sideswith separate blocks a, which are retained in place on the bolster bysuitable bands a which bands are held in place by bolts a passingthrough the bolster and retaining the bands in place. The bands arereadily detachable from the bolster in order to permit of their removalin order to substitute new blocks for those which may become worn inuse. Each block is provided with an opening passing entirely through itfrom top to bottom and which isdesigned to receive the king-bolt F. Thelower face of the bolster is provided with a plate a which rests uponand turns on a corresponding plate 6, attached to the crosspiece B ofthe hounds. Both the plates are provided with openings through which theking-bolt passes. The axle C has attached to it in any suitable manner,preferably in the same way as the bolster, blocks c,having openings ctherein, the openings in these blocks being arranged immediately belowthe openings in the blocks a.

The construction described is adapted for use in heavy two-horse wagonswhere a tongue is employed; but a similar construction may be 'used insingle-horse vehicles by providing the axle with a plate correspondingto that on the cross-piece of the hounds.

In the use of the gear, as described, the king bolt is passed througheither the forward or rear series of openings in the blocks describedand retained in place until the holes become worn sufficiently to leaveobjectionable play between the parts. After such wearing the king-boltis shifted to the other corresponding set of openings and retained thereuntil the parts through which it passes also become worn. When thistakes place, the blocks attached to the bolster and axle, respectively,are removed and new blocks substituted. The advantage of thisconstruction will be at once apparent to one skilled in the art, as bythis use a minimum amount of play between the parts of a wagon may bepreserved, and in case of wearing new blocks may be substituted forthose first used at a very inconsiderable expense.

Having thus described my invention, what I claim as new,'and desire tosecure by Letters Patent, is-

In a wagon running-gear the combination with the bolster and axle of twoblocks attached respectively to the forward and rear be removedindependently of the other, subsides of the bolster and axle, the blocksbeing stantially as described. 1 independent of each other and eachprovided In testimony whereof .I affix my signature with openings forthe reception of a king-bolt, in presence of two witnesses.
